sometimes, having a camera gets you out of real work
the biggest problem with both of these setups (at least for a newish beekeeper) is that it takes a LOT of wax to be able to dip the board(s) vertically.
don fatbeeman has a different method...he melts his wax in a tub filled with water, and dips horizontally. the amount of wax needed is only enough to float on top of the water. at first glance, it seems that it is much more work, as each dip only yields one sheet...but after dipping in wax, he dips in a water bath...pulling the board out of the water (again, horizontally) pulls the wax off the board and you are ready for the next dip.
i don't remember the yield, but with dee dipping, ramona embossing, and me trimming, we were cooking!
the melting vats are simply small metal barrels in a thermostatically controlled water bath.
